To ALL WHOM IT MAY ooNonRN:

Be it known that I, ABNER WHITELEY, of Springiield,in the county of Clark, and State of Ohio, invented a new and useful Improvement in Harvesters and I do hereby declare the following to be a full, clear, and vexact description of the same, reference being had to the accompanying drawings, in which v Figure 1 is a plan view of this machine.

Figure 2 is a rear view, showing in black the-position of the ringer-bar, roller, drivers seat, &c., when the driver is sitting on that end 0i' his seat nearest to the inger-bar, and in red lines the positions of the sameparts when the driver is on that end of his seat farthest from the iingerbar. V

This invention consists in constructing a harvesting-machine so as to enable the driver to use his seatas a lever, the lower peripheries of the ground-wheel and roller as fulcro., and his weight as the motive-power to raise or lower the Enger-bar in respect to the ground, whether the machine be moving forward, backward, or Standing still. i

That others may understand the construction and operation of this machine, I will particularly describe it.

.A is the main bearing and cutters driving-wheel; B is the roller at the inner end of the cutter-bar C, which forms the other hearing of the machine upon the ground when the cutter-bar is elevated therefrom; D

is the divers seat; I is the drivers foot-rest; F is the arm which connects the finger-bar'C to the main frame G- G; and Eis the brace-rod, which connects the finger-bar to the forward part of the main frame. In this application the spherical rollerB is placed on the arm F, which is an extension of the finger-bar O, but itis not necessarily so placed. It may be placed upon a separate axle, which maybe attached to the finger-bar in some secure and convenient manner. The brace-rod or drag-bar E connect-s the inner end of the finger-bar to the front end of the main frame, so as to relieve the arm F audits connection with the main frame from the eifects of side draught. The drivel-s foot-rest I is located just above the roller B, and the drivers seat D is mounted upon a standard elevated from the rear end of the main frame. This seat extends laterally on either side of the main frame, but extends farther on that side which is toward thenger-bar than on the other side. The wheel A and roller B form two bearings upon the ground, and a line which would connect their points of contact 'with the ground may he called the line of hearing. This line may be considered as forming the hypothenuse of.

n. triangle, ofwhich the line of the ii nger-har, (also through the point of contact of the roller 13,) may form the hase, and a line at right angles to this latter, cutting the point of'contact yof the wheel A, may be the prpendicular. l The seat D is parallel with'the base-line above mentioned. Now it is evident that supposing the hypothenuse line is in contact with the ground, it may form an axis of motion, and in that sense the base and perpendicular lines will both form levers, and their angle of meeting will be the long arm of this lever. If a.

certain weight be placed in front of this axis of motion, a certain other weight placed behind the said axis may or may not overcome it, as it is farther from or nearer to the axis. The finger-berend cutting-apparatus is a fixed weight in front of the axis above specified, and the driver upon his lscat is a. movable weight behind the same axis. If the drivers weight be sni'licicnt, that end of the machine will be depressed, moving upon the hypothenuse line as an axis, and the finger-'bar C will be elevated in a corresponding degree. The driver has it in his power at all times to place his weight at any point on his seat nearer to or farther from the axis upon which the machine moves, in raising or depressing' the cutting-apparatus, and hence he may use his seat as a lever, and himself as theweight to raise or depress the cutting-apparatus at pleasure, and ho may do this `whether the machine is moving forward, backward, or is standing still.

In operation the rollerB being situated about in line with the finger-bar, passes over undnlations of the ground, rising and falling at the same time that the cuttingapparatus rises or falls, and therefore the cutting apparatus will work moreV satisfactorily than it could were this roller either in front of or behind the cutterbar, as then they would be iniiu'enced by inequalities of the groundat diierent moments. In moving the machinefrom place to place, or in turning or backing it, or to clear obstructions,it is necessary to raise the cutting-apparatus from the ground, and this may be done at any time by moving the weight of the driverto the far 'end of his seat. The roller presses the cut grass down less than a'sliding shoe would do, and it is therefore preferable on that account. The globuiar shape of the rollen ,insures an equal surface Contact with the ground, in whatever position the finger-bar may be, a; result which could not be obtained with any ordinary forni of Wheel.

Having described this invention, what claim as new, and desire to secure by Letters Patent, is

1. Tho globular roller B, placed at theinner end of and in line with the @nger-bar of a harvesting-machine, in combination with vthe bearing-wheel A, vand the driver seat D, arranged and. operating substantially as desribed.

2. The 'globular roller B placed on the end of the nager-bm', in combination with said finger-bar, the main frame, brace-rod E, and driving-Wheel A, as set forth and described.
